Technique for Multiple Extractions

Technique for Multiple Extraction The surgical procedure for removing multiple adjacent teeth is modified slightly. The first step in removing a sin- . gle tooth is to loosen the soft tissue attachment from around the tooth (Fig. 8-5 1, A and B). When performing multiple extractions, the soft tissue reflection is extended slightly to form a small envelope flap to expose the’ erestal bone only (Fig. 8-51


POSTEXTRACTION CARE OF TOOTH SOCKET Once the tooth has been removed from the socket, it is necessary to provide proper care the socket should be debrided only if necessary If a periapical lesion is visible on the preoperative radiograph and there was. no granuloma attached to the tooth when it was removed, the periapical region should be carefully curetted to remove the granuloma or cyst. If any debris is obv

Modifications for Extraction of Primary Teeth

Modifications for Extraction of Primary Teeth It is rarely necessary to remove primary teeth before substantial root resorption has occurred. However, when removal is required, it must be done with a great deal of care, because. the roots of the primary teeth are very long and delicate and subject to fracture. This is especially true because the succedaneous tooth causes resorption of coronal portions of the

Mandibular molars

Mandibular molars The mandibular molars are usually two rooted, with. roots of the first molar more wide divergent than those of the· second molar. Additionally the roots may converge at the apical one third, which increases the difficulty of extraction. The roots are generally heavy and strong. The overlying .alveolar bone is heavier than the bone on any other teeth in the mouth. The combination of relativel

Mandibular premolars

Mandibular premolars The mandibular premolars are among the easiest teeth to remove. The roots tend to be straight and conic, albeit sometimes slender. The overlying alveolar bone- is thin on the buccal aspect and somewhat heavier on the lingual side. Extraction of mandibular left posterior teeth.

Mandibular interior teeth

mandibular interior teeth The mandibular incisors and canines are similar in shape, with the incisors being shorter and slightly thinner and the canine roots being longer and somewhat heavier. The incisor roots are more likely to be fractured, because they are somewhat thin and therefore should be removed only after adequate preextraction luxation. The alveolar bone that overlies the incisors and canines is

Mandibular Teeth

Mandibular Teeth When removing lower molar teeth, the index finger of the left hand is in the buccal vestibule and the second finger is in the lingual vestibule, reflecting the lip, cheek, and tongue (Fig. 7-65). The thumb of the left hand is placed below the chin so that the jaw is held between the fingers and thumb, which support the mandible and minimize TMJ pressures. This technique ‘provides less t

Maxillary molar

Maxillary molar The maxillary first molar has three large and relatively strong roots. The buccal roots are usually relatively close together, and the palatal root diverges widely toward the palate. If the two buccal roots are also widely divergent, it becomes difficult to remove this tooth by closed, or forceps, extraction. ‘Once again the overlying alveolar bone is similar to that of other teeth in the

Maxillary second premolar

Maxillary second premolar The maxillary second premolar is a single-rooted tooth for the root s entire length. The root is thick and has a blunt end. Consequently, the root of the second premolar fractures only rarely. The overlying alveolar bone is similar to that of other maxillary teeth in that it is relatively thin toward the bucca, with a heavy palatal alveolar palate. The recommended forceps is the maxi

Maxillary first premolar.

Maxillary first premolar The maxillary first premolar is a single-rooted tooth in its first two thirds. with a bifurcation into a buccolingual root usually occurring in the apical one third to one half. These roots may be extremely thin and’ are subject to fracture, especially in older patients in whom bone density is great and bone elasticity is small (Fig. 7-62).
